The picloc can most likely do this in perfect conditions, but you need to first aim the camera and then fly a circle at constant height, with the subject in center at all times.

For this to work without manual aiming of the camera you need to feed the gimbal controller with both its own and the subjects x,y and z coordinates. Then it can calculate where the subject is relative to the camera. I have not seen a gimbal controller do that yet, but a "point of interest" function exists in some systems like MK.

Edit: I have now read that the picloc has a GPS input. I need to find out more
